Structural geology: To stretch a continent

A Sketching Tool for Illustrative Structural Geology

We describe a sketch-based system for constructing an illustrative visualization of the subsurface. An intuitive and rapid modelling tool is defined, which takes as input user’s strokes and creates a 3D layer-cake model of the earth. Our tool enables users to quickly express and communicate their ideas directly using a 3D model. For sketching, we have created geometric operators that capture th...

Category Learning From Alignable Examples: An Application to Structural Geology

Geological forces shape the earth’s crust. Normal faults, for example, form when extensional forces pull blocks of rock apart along a plane, whereas reverse faults are formed by compressional forces. Geologists classify faults to retrace the forces that have acted on an area; however, normal and reverse faults often look similar. In this study we investigated whether viewing superficially simil...

Great challenges in structural geology and tectonics

Successful scientific theories provide theoretical understanding for reliable deterministic or probabilistic forecasting of events. In the past decades the volume of data obtained within the fields of structural geology and tectonics has increased enormously, but the theoretical understanding of the processes that generate these data has not advanced at the same rate. For example, after decades...
